are these amber bits on the headlights a legal requirement in the US as our UK cars do not have it?

Yes it's a law and it makes the headlights and side indicators look terrible. Going for UK spec headlights as soon as warranty is up. I've actually head some of the European guys LIKE the amber color? Weird

Not weird. Jus everyone wants what they can't have or what they don't get stock as apposed to other locations. We just always feel were missing something basically.
